PRlVY' -SEAT.

SPECIFICATION forming partof Letters Patent No. 428,001, dated May 13,1890. Application filed December 11, 1889. $erial No. 333,327. (Nomodel.) I

To aZZ whom it may concern:

Be it known that I, JOHN A. KALEY, a citizen of the United States,residing at Carson City, in the county of Montcalm and State ofMichigan, have invented a certain new and useful Improvement inPrivy-Seats, of which the following is a full,.clear, and exactdescription.

This invention relates to means for operating the cover or lid of theseat-hole in an ordinary box or pit privy, a water-closet, earthcloset,or other like apparatus wherever used.

The invention consists in a hinged cover or lid connected with a movingplatform upon which a person must needs stand in order to reach theseat, and whereby the lid is raised, combined with automatic devices forlowering the lid without noise, as I will proceed now to set forth, andfinally claim.

In the accompanying drawings, in the several figures of which like partsare similarly designated, Figure 1 is a vertical section showing myinvention applied to a box-privy. Fig. 2 is a sectional detail; Fig. 3,a section of a modified form of bellows-valve; Fig. 4, a perspectiveview of the spring-hinge, and Fig. 5 a perspective view of astench-tight pulley-box for the lid.

The seat a may be of usual construction and adapted to receive a box I)or be erected over a pit or receive a chamber-vessel.

c is the hole, and (Z is a cover for the hole. The cover is providedwith a strip 6 of felt or other soft or yielding material which fitsaround the hole when the lid is closed and prevents the escape ofstench, and which also renders the closing of the lid noiseless. lid issecured to the seat by a suitable number of hinges f, and I prefer touse springhinges-suoh, for example, as shown in Figs. 1 and 4, whichoperate to throw forward the raised lid to a point beyond the center ofgravity and so close it. In the example of springhinge shown the springf is coiled about the pin of the hinge, and one end is made fast to thehinge, while the other end f is free to act upon the lid when itis inorin the rear of a vertical plane, and when the lid passes forward ofthe vertical plane the free end of the spring becomes inert. I do notconfine the invention, however, to a spring-hinge for the lid, or indeedto any kind of hinge or to The any particular kind of spring. Acord,chain, or other flexible connection g is attached by one end to thehinged end of the lid, and extends thence over pulleys h e to andbeneath the seat, and thence forward under the seat to a pulley j, andthence downward along the riser 7a to a projection Zof the trap orplatform m, so that by depressing the platform the cover will be raised,and by allowing the platform to rise the lid will fall. The pulleys 7Land '2' are arranged in a casin g n, whereother mediums, and under itsfree end is arranged a bellows or other equivalentresilientor yieldingmedium 1), which will retard the rise of the platform, so as to retardthe fall of the lid, and hence prevent its slamming.

In the case of the bellows, it may be made with a flap-valve q, ventingthrough the platform, or with a ball-valve, Fig. 3, similarly venting.The bellows is' provided witha finger 0, which upon the release andrising of the platform and the descent of the lid or cover catchesagainst a projection s on the riser to insure the retarding of therising of the platform, and so effect the easy and noiseless closing ofthe lid, or a strap may be used for the same purpose.

The projection Z of the platform plays in a slot '6 in the riser, andthis slot is covered with a piece of flexible stuff u-to prevent theescape of stench.

Instead of arranging the bellows or its equivalent under the platform,it might be arranged under the lid or interposed in the connection g.

hat I claim is- 1. The combination, with a privy or watercloset seat, ofthehinged lid or cover, a hinged platform or trap, a flexible connectionbetween the lid and platform, and a resilient medium, such as a bellows,interposed beneath the platform, a finger r on the bellows, and a fixedstops, engaged by said finger, just before the lid completes its fall,thereby to I 5 case the descent of the lid, substantially as described.

In testimony whereof I have hereunto set myhand this 25th dayofNovember, A. D. 1889.

JOHN A. KALEY.
